Sure, I use the same technique sometimes as well.
As an alternative to returning a String you could also pass the bean a
PrintWriter or use a StringBuffer.
That way you avoid excessive sting addition (which is bad for performance).
It's better than a design where you pass request and/or response to your
bean, because that would make your classes too much dependent on the
'servlet' context.
